This paper presents an H.323 standard compliant virtual video conferencing system.The proposed system not only serves as a multipoint control unit (MCU) for multipoint connection but also provides a gateway function between the H.323 LAN (local-area network) and the H.324 WAN (wide-area network) users.

The proposed virtual video conferencing system provides user-friendly object compositing color block iphone case and manipulation features including 2D video object scaling, repositioning, rotation, and dynamic bit-allocation in a 3D virtual environment.A reliable, and accurate scheme based on background image mosaics is color touch 7/97 proposed for real-time extracting and tracking foreground video objects from the video captured with an active camera.Chroma-key insertion is used to facilitate video objects extraction and manipulation.We have implemented a prototype of the virtual conference system with an integrated graphical user interface to demonstrate the feasibility of the proposed methods.
